Therese Coffey: My understanding is that the policy relates to people who have had child maintenance arrangements for a very long time. There comes a point when there is an element of understanding the different debts. My hon. Friend will be aware that, in a way, this is a very odd arrangement, with the state effectively becoming the arbiter between two parents. The only people who lose are the children. That is why I encourage everybody who has a responsibility towards their children—currently 111,000 children are owed £187 million by parents who refuse to pay up—to get on and do the right thing by them. We should not end up having to rely on the state to arbitrate between two parents.
